Abstract

Abstract This application discloses a tiling system for surfaces where the pattern of the tiling changes continuously from one portion of the tiling to another in an Escher-like metamorphoses with the difference the the metamorphoses are based on binary combinations of n transformations on the edges of the tile. Accordingly, the tiling is obtained from the n directions of the edges of an underlying zonohedron, a polyhedron derived as a projection of an n-dimensional cube. The zonohedron provides a hidden network for the continuous transformations of the tiles to one another. The derived designs utilize 3- and 4-sided polygons and have a variety of curved edges in and across the plane of the tile. The metamorphic designs provide visually attractive alternatives to periodic patterns used as architectural surfaces, walls, floors, ceilings, window screens and dividers, architectural space enclosures, visual art, textile designs and computer graphics amongst other varied applications.

Total Claims: 20
Claim 1
Independent Claim 373 words
A method of producing metamorphic tiling patterns for various design applications and comprising: a plurality of transformed polygons derived from a base tiling pattern composed of plane-filling base polygons wherein said transformed polygons are obtained by applying geometric transformations on the edges of said base polygons wherein each said transformed polygon is a geometric transformation of the adjacent transformed polygon and said plurality of transformed polygons displays a gradual transformation of the tiling pattern from one portion of the pattern to another, where said geometric transformations are binary combinations of n distinct geometric transformations performed on edges of said base polygons, where the said plurality of said transformed polygons cover a surface of an underlying zonohedron network composed of contiguous parallelogram faces and defined by a projection of an n-dimensional cube having edges parallel to n directions, such that each direction is coupled with an associated geometric transformation, and where n is any number greater than 3, where the said metamorphic tiling pattern is derived by using the method steps comprising the following: selecting said base tiling pattern composed of plane-filling 4-sided base polygons of desired proportions and angles, projecting said n-dimensional cube onto said base tiling pattern, identifying sets of said base polygons as vertex-polygons corresponding to the vertices of said projected n-dimensional cube, edge-polygons corresponding to the edges of said projected n-dimensional cube, and face-polygons corresponding to all remaining polygons which are not vertex- and edge-polygons, performing a first transformation on each said vertex-polygon whereby n independent geometric transformations are selected and their combinations applied to all said vertex-polygons thereby creating a set of transformed vertex-polygons, selecting a sub-set of said transformed vertex-polygons corresponding to the vertices of said contiguous parallelogram faces of said zonohedron network, performing a second transformation whereby all said edge-polygons corresponding to the edges of the said zonohedron network are transformed by gradual incremental transformations between said transformed vertex-polygons thereby creating a set of transformed edge-polygons, performing a third transformation whereby all said face-polygons corresponding to the faces of the said zonohedron network are transformed by gradual incremental transformations between said transformed vertex- and edge-polygons, where said method steps are applied systematically over the entire surface of the said zonohedron network to generate said metamorphic tiling pattern.
